Hi,
I execute the following code snippet.What I don't understand is, that in the
first two cases the numbers shown don't correnspondant to the input (though
I have set the options to show 22 digits). When I assign the third number
which has one place, the display of the numbers is suddenly correct.
Can anybody explain what happens here?
(this is just a sample, my real problem lies in numbers that I import from a
datafile and I don't know how to control them when this switching occurs)
###########################
options( digits=22 )
x <- matrix(NA, 3,1)
x[1] <- 6.94788635771657950
x # 6.947886357716580 # DIFFERENT ???
# NA
# NA
x[1] == 6.94788635771657950 # but is the same
x[2] <- 8.34284937565404050
x # 6.947886357716580 # DIFFERENT ???
# 8.342849375654041 # DIFFERENT ???
# NA
x[1] == 6.94788635771657950 # but is the same
x[3] <- 0.19043842368566377
x # 6.94788635771657950 # NOW OK!!!
# 8.34284937565404050 # " "
# 0.19043842368566377 # " "
x[1] == 6.94788635771657950 # but is the same
